Abstract

The chair has an inclinable seat support, and an inclinable backrest supported by a backrest support. A crank contour (14) forms a rectangle with four straight sides which are connected with each other at round corners. A flange (12) of a collar (9) forms an equilateral triangle with the three straight sides that are connected with each other at round corners. The round corners of the collars lie in upper and lower positions of the collar in the front upper and lower corner of the contour. The corners of the flange are supported at the contour during upward and downward movement of the collar.

Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft einen Stuhl mit neigbarem Sitz und einer neigbaren, von einem Lehnenträger getragenen Lehne. Solche Stühle sind wichtig nicht nur für den Bürobereich, wo der Benutzer den Stuhl unter ergonomischen Aspekten seiner jeweiligen Arbeitsstellung anpassen können muss, sondern auch im privaten Bereich, wo der Benutzer die jeweilige Sitz- und Lehnenneigung zum Zwecke der Entspannung ändern möchte.The invention relates to a chair with tiltable seat and a tiltable, carried by a backrest backrest. Such chairs are important not only for the office area, where the user needs to be able to adjust the chair under ergonomic aspects of their respective working position, but also in the private area, where the user wants to change the particular seat and backrest angle for the purpose of relaxation.

STAND DER TECHNIKSTATE OF THE ART

Stühle mit neigbarem Sitz und neigbarer Lehne sind zum Beispiel aus EP-A 0834271 . EP-B 0489961 oder EP-B 0233974 bekannt. Die aus diesen Druckschriften bekannten Stühle weisen neigbare Sitze und Lehnen auf, wobei Sitz und Lehne zwangsgekoppelt sind. Man spricht insoweit auch von "Synchronmechanik".For example, chairs with reclining seats and reclining backrests are off EP-A 0834271 , EP-B 0489961 or EP-B 0233974 known. The chairs known from these documents have tiltable seats and backrests, the seat and back being forcibly coupled. In this respect one speaks of "synchronous mechanics".

Diese Stühle haben sich in der Praxis hervorragend bewährt. Sie sind jedoch insoweit noch nicht optimal, als der Benutzer an das durch die Synchronmechanik vorgegebene Neigungsverhältnis von Sitz und Lehne gebunden ist. Es ist dem Benutzer nicht möglich, die Lehnenneigung in einer bestimmten Stellung einzustellen, und bei einer solchen Stellung die Neigung des Sitzes zu verändern.These chairs have proven themselves in practice outstanding. However, they are not yet optimal insofar as the user is bound by the predetermined by the synchronous mechanism inclination ratio of the seat and backrest. It is not possible for the user to adjust the backrest tilt in a certain position, and to change the inclination of the seat in such a position.

Es wurde deshalb ein Stuhl entwickelt, der in der EP-A 1192876 beschrieben ist, und bei dem an der Unterseite des Sitzes ein Lagerbock vorgesehen ist, in welchem eine Scheibe drehbar gelagert ist, die von einem Sechskantstab mit Handgriff exzentrisch durchtreten wird, der in einem Arm am Lehnenträger gelagert ist. Diese bekannte Konstruktion hat sich gut bewährt. Sie weist jedoch den Nachteil auf, dass beim Verstellen der Sitzneigung der Sitz eine Horizontalbewegung ausführen muss, was konstruktiv unerwünscht ist, da es die Konstruktionsfreiheit bei der Lagerung des Sitzes, insbesondere an der Vorderkante, einschränkt.It was therefore developed a chair that in the EP-A 1192876 is described, and in which a bearing block is provided on the underside of the seat, in which is rotatably mounted a disc which is eccentrically pass through a hexagonal rod with handle, which is mounted in one arm on the backrest support. This known construction has proven itself well. However, it has the disadvantage that when adjusting the seat angle of the seat must perform a horizontal movement, which is structurally undesirable because it limits the design freedom in the storage of the seat, especially at the front edge.

Die bekannte Konstruktion wurde deshalb wie in der EP-A 1576905 beschrieben weiterentwickelt: Der Grundgedanke der Weiterentwicklung besteht in der Idee, bei der Abstützung des Sitzes auf dem Lehnenträger die Distanz zwischen Sitz und Lehnenträger durch eine spezielle Lagerung geradlinig von Hand veränderbar zu machen. Damit folgt zwar der Sitz prinzipiell der Neigung der Lehne, kann aber hinsichtlich seiner Neigung zusätzlich noch individuell eingestellt werden, ohne eine Horizontalbewegung auszuführen. Konstruktiv weist hierzu der Lagerbock an der Unterseite des Sitzes ein vertikales Langloch sowie eine Kulissenkontur auf, wobei der Bund des Hubelementes in dem Langloch geführt ist, und der Kragen des Hubelementes bei der Bewegung des Bundes auf der Kulissenkontur gleitet. Jedoch ist auch diese Lösung noch nicht optimal, da sie bei starken Be- oder Entlastungen keine maximale Stabilität aufweist. Hier soll die Erfindung Abhilfe bringen.The well-known construction was therefore as in the EP-A 1576905 described further developed: The basic idea of the further development consists in the idea, with the support of the seat on the backrest support the distance between seat and backrest support by a special storage straightforward by hand to change. Thus, while the seat in principle follows the inclination of the back, but can also be adjusted individually in terms of its inclination, without performing a horizontal movement. Structurally, for this purpose, the bearing block on the underside of the seat on a vertical slot and a link contour, wherein the collar of the lifting element is guided in the slot, and the collar of the lifting element slides in the movement of the covenant on the backdrop contour. However, even this solution is not optimal, since it has no strong stability under heavy loading or unloading. Here is the invention to remedy the situation.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Es ist demnach die Aufgabe der Erfindung, einen Stuhl mit neigbarem Sitz und neigbarer Lehne, bei dem die Neigung des Sitzes unabhängig von der durch eine Synchronmechanik in Abhängigkeit von der Lehnenneigung gegebenen Neigung individuell eingestellt werden kann, derart weiter zu verbessern, dass der Sitz maximale Stabilität aufweist. Dabei muss die erfindungsgemäße Konstruktion wenig aufwendig und im Produktionsprozess leicht herstellbar sein, und muss des weiteren auch optisch-ästhetisch voll befriedigen.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 und der Unteransprüche gelöst.It is therefore an object of the invention to provide a chair with tiltable seat and tilting back, in which the inclination of the seat can be adjusted independently of the given by a synchronous mechanism in response to the backrest inclination individually to further improve so that the seat maximum Stability. In this case, the construction according to the invention must be inexpensive and easy to manufacture in the production process, and must also fully satisfy the aesthetic and aesthetically pleasing.
This object is solved by the features of claim 1 and the dependent claims.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS FOR CARRYING OUT THE INVENTION

Die Hauptbestandteile des in Fig.1 und Fig. 2 gezeigten Stuhles sind der Sitz mit dem Sitzträger 1, die Lehne 2 mit Lehnenträger 5, das Neigemechanik-Gehäuse 4, und die Standsäule 3.The main components of in Fig.1 and Fig. 2 shown chair are the seat with the seat support 1, the backrest 2 with backrest support 5, the tilting mechanism housing 4, and the pillar. 3

Sitz und Lehnenträger 5 mit Lehne 2 sind über die Neigemechanik und die gelenkige Anbindung des Sitzträgers 1 an den Lehnenträger 5 in bekannter Weise bezüglich ihrer Neigung zwangsgekoppelt. Wenn also die Lehne 2 und mit ihr der Lehnenträger 5 nach hinten geneigt wird, so senkt sich auch der Sitzträger 1 ab.Seat and backrest support 5 with back 2 are forcibly coupled via the tilting mechanism and the articulated connection of the seat support 1 to the backrest support 5 in a known manner with respect to their inclination. So if the backrest 2 and with it the backrest support 5 is tilted backwards, so also the seat support 1 lowers.

Die gelenkige Anbindung des Sitzträgers 1 an den Lehnenträger 5 besteht nun aber erfindungsgemäß aus den Elementen 7-14, die im Detail in Fig.3, 4 und Fig.5 gezeigt sind:The articulated connection of the seat support 1 to the backrest support 5 but consists according to the invention of the elements 7-14, which in detail in Figure 3 . 4 and Figure 5 shown are:

An der Unterseite des Sitzträgers 1 sind jeweils links und rechts ein Lagerbock 10 vorgesehen, der ein Langloch 13 und eine Kulissenkontur 14 aufweist. Am Lehnenträger 5 sind jeweils links und rechts Lager 6 vorgesehen. Ferner ist der Stab 8 vorgesehen, der als Sechskant ausgebildet ist, und auf dessen beiden Enden mit dem Bund 9 jeweils das Hubelement 7 aufgesteckt ist. Da auch der Bund 9 als Sechskant ausgeführt ist, sitzt das Hubelement 7 unverdrehbar auf dem Stab 8. Im fertig montierten Zustand durchtritt der Stab 8 der Reihe nach den ersten Lagerbock 10, das erste Lager 6, das zweite Lager 6, und dann den zweiten Lagerbock 10. In den Langlöchern 13 der Lagerböcke 10 ist jeweils der Bund 9 des Hubelementes 7 höhenbeweglich geführt, und der Kragen 12 ist innerhalb der Kulissenkontur 14 bewegbar.On the underside of the seat support 1, a bearing block 10 are respectively provided on the left and right, which has a slot 13 and a link contour 14. On the backrest support 5 bearings 6 are provided on the left and right. Furthermore, the Rod 8 is provided, which is designed as a hexagon, and on the two ends of the collar 9, the lifting element 7 is attached in each case. As well as the collar 9 is designed as a hexagon, the lifting element 7 sits non-rotatably on the rod 8. In the assembled state passes through the rod 8 in order the first bearing block 10, the first bearing 6, the second bearing 6, and then the second Bearing 10. In the slots 13 of the bearing blocks 10 each of the collar 9 of the lifting element 7 is guided vertically movable, and the collar 12 is movable within the link contour 14.

Damit das Hubelement 7 vom Benutzer des Stuhles betätigt werden kann, weist es den Handgriff 11 auf.So that the lifting element 7 can be actuated by the user of the chair, it has the handle 11.

Wie insbesondere aus Fig.5 ersichtlich ist, weist das Hubelement 7 des weiteren den Kragen 12 auf, der aus einem umlaufenden im wesentlichen die Form eines gleichseitigen Dreiecks mit runden Ecken aufweisenden Steg besteht, in dessen einer Ecke der Bund 9 sitzt. Korrespondierend dazu weist der Lagerbock 10 das Langloch 13 und die Kulissenkontur 14 auf. Die Kulissenkontur 14 weist annähernd die Form eines Rechtecks mit runden Ecken auf, dessen eine Seite parallel zum Langloch 13, und dessen andere Seite horizontal oberhalb des Langlochs 13 verläuft. Zur Montage wird das Hubelement 7 mit dem Bund 9 in das Langloch 13 eingeführt, wobei der Kragen 12 innerhalb der Kulissenkontur 14 zu liegen kommt.As in particular from Figure 5 it can be seen, the lifting element 7 further comprises the collar 12, which consists of a circumferential substantially the shape of an equilateral triangle with rounded corners having web, sitting in one corner of the collar 9. Corresponding thereto, the bearing block 10, the slot 13 and the link contour 14. The link contour 14 has approximately the shape of a rectangle with rounded corners, one side of which runs parallel to the slot 13, and the other side extends horizontally above the slot 13. For assembly, the lifting element 7 is inserted with the collar 9 in the slot 13, wherein the collar 12 comes to rest within the backdrop contour 14.

Die Lagerung des Sitzträgers 1 an der Vorderkante erfolgt über die Sitzlager 15 an der Sitzlagerachse 16.The storage of the seat support 1 at the front edge via the seat bearing 15 on the seat bearing axis sixteenth

Im Betrieb funktioniert die erfindungsgemäße Mechanik wie folgt:In operation, the mechanism according to the invention functions as follows:

Wenn der Sitzträger 1 mit seiner Hinterkante abgesenkt ist, wie dies in Fig.1 dargestellt ist, dann befindet sich der Bund 9 des Hubelementes 7 im Langloch 13 in der oberen Position. Der Kragen 12 verläuft mit seiner vorderen Seite parallel zum Langloch 13 und liegt mit seiner unteren runden Ecke in der unteren runden Ecke der Kulissenkontur 14. Der Handgriff 11 steht senkrecht, wie in Fig.5 gezeigt.When the seat support 1 is lowered with its trailing edge, as shown in FIG Fig.1 is shown, then there is the collar 9 of the lifting element 7 in the slot 13 in the upper position. The collar 12 extends with its front side parallel to the slot 13 and lies with its lower round corner in the lower round corner of the link contour 14. The handle 11 is vertical, as in Figure 5 shown.

Soll nun der Sitzträger 1 mit seiner Hinterkante gegenüber dem Lehnenträger 5 gehoben werden, wie in Fig.2 gezeigt, so wird das Hubelement 7 mittels des Handgriffs 11 nach hinten, im Gegenuhrzeigersinn gedreht. Dabei bewegt sich die untere runde Ecke des Kragens 12 zur unteren hinteren runden Ecke der Kulissenkontur 14, rastet dort ein und definiert deren Rastpunkt. Bei weiterer Bewegung wird diese obere Position verriegelt, sodass keine selbständige Verstellung des Mechanismus mehr stattfinden kann.If now the seat support 1 is lifted with its rear edge opposite the backrest support 5, as in Fig.2 shown, the lifting element 7 is rotated by the handle 11 to the rear, in the counterclockwise direction. It moves the lower round corner of the collar 12 to the lower rear round corner of the backdrop contour 14, snaps in there and defines their resting point. Upon further movement, this upper position is locked, so that no independent adjustment of the mechanism can take place more.

Zum Absenken der Hinterkante des Sitzträgers 1 wird dann der Handgriff 11 wieder in seine vertikale Position gebracht. Dabei stützt sich der Kragen 12 mit seinen runden Ecken wieder auf der Kulissenkontur 14 ab, und der Bund 9 erfährt eine nach oben gerichtete Kraft. Dabei hilft zusätzlich die auf den Lagerbock 10 wirkende Gewichtskraft des Stuhl-Benutxers. In der Endstellung hat dann das Hubelement 7 wieder die in Fig.5 gezeigte Position. Da das Hubelement 7 und der Lagerbock 10 nicht unbeachtliche Kräfte übertragen müssen, bestehen sie aus glasfaserverstärktem Polyamid. Der Stab 8 besteht aus StahlTo lower the rear edge of the seat support 1, the handle 11 is then returned to its vertical position. Here, the collar 12 is supported again with its round corners on the link contour 14, and the collar 9 undergoes an upward force. In addition, the force acting on the bearing block 10 weight of the chair Benutxers helps. In the end position then the lifting element 7 again in Figure 5 shown position. Since the lifting element 7 and the bearing block 10 do not have to transmit unimportant forces, they consist of glass fiber reinforced polyamide. The rod 8 is made of steel

Mit der Erfindung werden ersichtlich die aufgabengemäß angestrebten Vorteile in hohem Maße erreicht: die beiden Endstellungen der Höhenverstellung sind absolut stabil, eine selbständige Entriegelung ist ausgeschlossen.With the invention, the objects according to the objects sought are clearly achieved to a high degree: the two end positions of the height adjustment are absolutely stable, a self-unlocking is excluded.
